My cousin moved to America when he had just graduated. After his sisters were married off, his parents started looking for a bride for him and zeroed it upon a girl who promised to follow her husband when ever he wished to come and settle in India. The girl appeared to be sweet and was wealthy (or so they thought). The wedding was fixed and everybody were happy.

After the wedding and a short honeymoon to a domestic destination, they both flew to America. Everything went on fine, until she expressed her desire to work. She had to upgrade her studies to be able to work and it took her 5 years or so in doing that. My cousin supported her throughout. The plans to start a family was pushed off because she wanted to build a career. After 12 years of marriage they were blessed with a baby boy.
My cousin meanwhile thought that his kid would be raised better in India where his parents were getting old and were alone. He had a talk with his wife, who told him that he could move back anytime without the kids, home and her. Well, that's all he had. So, he was forced to live there while his parents lost hope that they will ever have the support of their son when the time needs.
Now my cousin's son is around 10 years old and cannot speak a bit of mother tongue. His parents speak the language fluently, but it seems like they never wanted their son to learn the language and culture. When asked, they claimed that the kid speaks English at school and that continues at home. Now, our kids also speak English and Hindi at school, how do they learn mother tongue then ? Well, that's what I think is the greatest mistake that these Indian Americans do. They don't teach their children our cultures and languages.
